I stayed in a suite in this hotel for about a week.
The suite was very clean and comfortable. Wi-Fi was working perfectly, the kitchen was well equipped and the furniture very modern. Housekeeping every day and they would have even delivered groceries to the suite.
Also there wasn't too much noise from the other suites, most nights it was very quiet.
The only thing I disliked was the breakfast buffett because mostly there was only sweet food, like pastries or waffles. The selection of savory food was very small, so I went out for breakfast on most mornings.
The location of the hotel is amazing. It's not too far from the city center, a bus station is right on the other side of the street. The ride costs 2$ and takes about 40 minutes.
In Arlington there are a lot of nice cafés, restaurants and diners, so there is no need for a longer trip for food. Also there are grocery stores close by. Easily reachable by walking for a few mins.
I've been to Arlington 4 times, it is perfectly possible to get anywhere by bus or Uber.
I would recommend this hotel and stay here again on my next trip to Boston.
